  The 4500 was the first MIPS-based Cisco router I saw.  While I don't
know that it was the first, it does predate the 3600 and 7200 families
by quite a few years.  It followed the 4000, which was 68K-based.

  10.x can indeed run on the AGS+.  I've never seen it on any smaller
*GS router.

  Yeah but it's still IOS, and still looks a whole lot like TOPS-20. :-)
